织物变形的物理仿真技术

基于物理的仿真模型是织物变形仿真技术的主流 .文中对基于物理的织物变形仿真模型进行了综述 .首先 ,把模型分为两类 :一类是离散质点型模型 ,一类是连续介质型模型 .其次 ,评述了各种模型 ,分析了其优缺点 ,并对各种算法的效率进行了比较 .最后 ,对织物变形物理的仿真的发展方向提出了一些看法 ,特别强调了发展有限元模型 .

Quality Characteristics Distribution and Its Simulation Based on Asymmetric Tolerances

The application of normal distribution for quality characteristics has its limits on the condition that specification interval is asymmetric. In this paper, the compound normal distribution N(L,σ12,σ22) was proposed and simulated, the property of the parameters Lσ1 and σ2 was studied. The distribution was further applied toangle quality process control.
